ACCA’s 2015 HVAC Quality Installation Specification Standard Recognized by ANSI

August 3, 2015

The Air Conditioning Contractors of America Educational Institute Standards Task Team announced that the American National Standards Institute (ANSI) has recognized the updated ANSI/ACCA 5 QI (HVAC Quality Installation Specification) Standard.

Drawing on an extensive committee – comprised of volunteers from mechanical contractors, utility program administrators, original equipment manufacturers, State and Federal entities, allied associations, and other interested stakeholders – the prior 2010 standard was revised to include new procedures / approaches, streamline the instruction set, clarify language, and update references / citations.

The revised ACCA 5 QI - 2015 Standard recognizes that a quality installation is more than just using high-efficiency products and systems.  The correct design, proper installation, and final testing have a large impact on occupant satisfaction and energy savings. The standard defines a level of performance that, if satisfactorily achieved, serves as an indicator that sound industry practices were followed during the design and equipment installation phases. The core areas that characterize a quality installation are the design aspects, equipment installation aspects, distribution aspects, and system documentation and owner education aspects.

The Standard details the nationally-recognized minimum criteria for the proper installation of HVAC systems in residential and commercial applications.  Its requirements are applicable to the following equipment types:

  • Unitary air conditioners, air-source/water-source heat pumps, and geothermal heat pumps;
  • Furnaces (gas-fired, oil-fired, electrics, and other);
  • Boilers (gas-fired, oil-fired, electric, and other).

Also updated is the Technician’s Guide & Workbook for Quality Installation; it was revised to reflect the changes made in the QI Standard – 2015. The Guide & Workbook is ‘user guide’ that supports technicians implementing the ACCA 5 QI Standard in the field as well as being a valuable teaching tool that can be used in a classroom environment.

Interested persons can download a free copy of ANSI/ACCA 5 QI - 2015 (HVAC Quality Installation Specification) at   Printed copies of the QI Standard and the Technician’s Guide & Workbook are sold through the ACCA bookstore at
